1. A display control apparatus comprising:
- a detection unit configured to detect a touch operation and a move operation without releasing on a display unit;
a display control unit configured to control a display screen to be displayed on the display unit, the display screen including a plurality of items including a first item enabling a user to change a setting value in response to the touch operation in an area of the first item without screen transition, and a second item enabling the display screen to transition to a different display screen in response to the touch operation in an area of the second item;
a selection unit configured to select one of the plurality of items in response to the touch operation detected by the detection unit; and
a control unit configured to,(a) in a first case where the first item has been selected by the selection unit and a touch-down operation for touching the display screen is detected in the area of the first item by the detection unit, change a setting value corresponding to the first item in response to the move operation in the first direction continuing from the touch-down operation, and control the selection unit not to change the selected item in response to the move operation in the second direction continuing from the touch-down operation,(b) in a second case where the second item has been selected by the selection unit and a touch-down operation is detected in the area of the second item by the detection unit, control the selection unit to change the selected item in response to the move operation in the second direction continuing from the touch-down operation,(c) in a third case where the first item has not been selected by the selection unit and the touch-down operation for the display screen is detected in the area of the first item by the detection unit, control the selection unit not to change the setting value corresponding to the first item even if the move operation in the first direction continuing from the touch-down operation is performed, and control the selection unit to change the selected item in response to the move operation in the second direction continuing from the touch-down operation.

Abstract
A display control apparatus enables a user to perform a touch operation more simply and easily on a screen including a first item permitting a setting change without screen transition and a second item permitting a setting change after transition of the screen to a different display screen. On a display screen with a plurality of items including the first item and the second item, when a touch-down operation is detected in an area of the first item while the first item is selected, the display control apparatus invalidates a move operation for selecting other items. On the other hand, when a touch-down operation is detected in an area of the second item while the second item is selected, the display control apparatus validates a move operation for selecting other items.

9. A method for controlling a display control apparatus, the method comprising:
-
detecting a touch operation and a move operation without releasing on a display unit; controlling a display screen to be displayed on the display unit, the display screen including a plurality of items including a first item enabling a user to change a setting value in response to the touch operation in an area of the first item without screen transition, and a second item enabling the display screen to transition to a different display screen in response to the touch operation in an area of the second item; selecting one of the plurality of items in response to the touch operation detected by the detecting; and controlling, (a) in a first case where the first item has been selected by the selecting and a touch-down operation is detected in the area of the first item by the detecting, to change a setting value corresponding to the first item in response to the move operation in the first direction continuing from the touch-down operation, and not to change the selected item in response to the move operation in the second direction continuing from the touch-down operation, (b) in a second case where the second item has been selected by the selecting and a touch-down operation is detected in the area of the second item by the detecting, the selecting to change the selected item in response to the move operation in the second direction continuing from the touch-down operation, and (c) in a third case where the first item has not been selected by the selecting and the touch-down operation for the display screen is detected in the area of the first item by the detecting, to control the selecting not to change the setting value corresponding to the first item even if the move operation in the first direction continuing from the touch-down operation is performed, and to control the selecting to change the selected item in response to the move operation in the second direction continuing from the touch-down operation.

10. A non-transitory computer-readable storage medium storing a program that causes a computer to execute a method for controlling a display control apparatus, the method comprising:
-
detecting a touch operation and a move operation without releasing on a display unit; controlling a display screen to be displayed on the display unit, the display screen including a plurality of items including a first item enabling a user to change a setting value in response to the touch operation in an area of the first item without screen transition, and a second item enabling the display screen to transition to a different display screen in response to the touch operation in an area of the second item; selecting one of the plurality of items in response to the touch operation detected by the detecting; and controlling, (a) in a first case where the first item has been selected by the selecting and a touch-down operation is detected in the area of the first item by the detecting, change a setting value corresponding to the first item in response to the move operation in the first direction continuing from the touch-down operation, and control the selecting not to change the selected item in response to the move operation in the second direction continuing from the touch-down operation, (b) in a second case where the second item has been selected by the selecting and a touch-down operation is detected in the area of the second item by the detecting, the selecting to change the selected item in response to the move operation in the second direction continuing from the touch-down operation, and (c) in a third case where the first item has not been selected by the selecting and the touch-down operation for the display screen is detected in the area of the first item by the detecting, to control the selecting not to change the setting value corresponding to the first item even if the move operation in the first direction continuing from the touch-down operation is performed, and to control the selecting to change the selected item in response to the move operation in the second direction continuing from the touch-down operation.
